This invention pertains to car trucks and has for its object to providemeans whereby the wheels on each side of the truck may rotateindependently of each other. We accomplish this purpose by providing aseparate and distinct axle for each wheel. The desirability ofindependent rotation of each wheel is obvious, such as the preventing ofthe dragging of a portion of the wheels in going around a curve therebysaving power and preventing the wearing of the wheels and forming fiatsurfaces thereon.

The invention will be hereinafter particularly described and illustratedin the accompanying drawings, in which- Figure 1, is a top plan view ofthe im- 'proved truck resting upon broken-away portions of rails, Fig.2, is a side elevation of the same and a broken-away sectional view ofthe base of the car body to which the truck is attached, Fig. 3, is aside view of the boxing in which inner ends of the axles are journaledtogether with a sectional View of one of the axles, showing also bydotted lines the open position of the cap to the boxing, Fig. 4, is asectional View taken on the line 4- 1 of Fig. 3, and Fig. 5, is an endview of the said boxing together with broken-away views of two shaftsjournaled therein.
